辐射流体动力学方程包含松弛项以及辐射通量、粘性应力以及介质的加速度和角速度之间的耦合,是从 14 矩近似推导出来的。讨论了造成体积粘度的物理机制。
The equations of radiative hydrodynamics, with inclusion of relaxation terms and couplings between the radiative flux, viscous stresses and the acceleration and angular velocity of the medium, are derived from the 14- moment approximation. The physical mechanism responsible for the bulk viscosity is discussed.
